SUPPORT FOR NAIIQI G s'rmrs AND HE L KE.

Application filed April 12, 1926. Serial No. 101,367.

This invention relates to supports for nailing strips or screeds used in building construction, and the invention aims generally to improve such devices.

In the accompanying drawings, 1. have illustrated the invention as used in connection with a common type of composite fioorconstruction, embodying expanded metal reinforcement for the .fioor slab, wherein the screed support may also serve as a means for positioning or securing the expanded metal sheets with reference to the floor beams.

In the drawings, 7 I

Fig. 1 is a tragmental cross-sectional view oi the framework and reinforcement of a steel, concrete and wood floor, illustrating one manner of use of the embodiment of my invention selected for illustration herein;

Fig. 2 is a perspective view of the improved chair or supporting clip v used in the floor shown in Fig. 1, and illustrates a type of chair applicable to structures of various kinds for supporting soreeds arranged at right ajngles to the beams;

Fig. 3 is a planviewot a similar chair for supporting a screed arrangedparallel to the beam; and V Fig.4 is a cross-section of the same on the line 4:4 in Fig. 3.

The type offloor construction illustrated in the accompanying drawings, and to which my invention is particularly adapted, preferably includes beams or joists 10 of I-section or other suitable flanged structural shape, as for instance channels, Zs and Ts, spaced at suitable intervals for supporting the. floor slab. The construction mayadvantageously comprise centering, illustrated as sheets of I lath 11 preferably of metal, upon'which the concrete or other cementitious filling is poured to form the floor slab, as is well known in the building art; but the use of permanent centering is not essential, as the floor slab may be formed without it in any convenient manner known to the art.

The wooden screeds or nailingstrips 12, to which the wooden flooring 13 is secured, are preferably supported above the tops of the beams and spaced from the lath or other centering 11 in order to permit of forming a continuous layer of concrete over the entire area of the floor, and thereby protecting the beams from fire and preventing vermin from boring through the floor. I

The invention aims to provide a chair or supporting clip which may be readily attached to and supported by the flanges of the beam or joist, and which will securely hold the screed or nailing strip at spaced points with suflicient rigidity to support therunways for use by the workmen when pouring the concrete or other filling. The chair may also assist in positionin ecurely the sheets of metal lath or the likii with respect to the beams until theconcrete has set. 1 i In the formot invention illustrated in Figs. 1 and 2, the support 15 is so shaped as to constitute a combined clip and chair, and is preferably constructed of a single piece of heavy gauge wire. The wire is so bent or otherwise shaped asto provide atits middle a U-shaped supporting seat 16 for the screed or nailing strip 12. The sides of the chair extend upwardsand are preferablyspaced apart a distance'sufi'icientto receive snugly between them, screeds' or nailing strips 12 which are commonly of standard size. The upper extremities of the sides of the 'U-shapedportion' 16 are reverse'ly bent and extendeddownwardly to provide supporting legs 17 and 18, which terminate in hook-shaped feet 19 andQO, extending laterally parallel to each other and at right angles to the legs 17 and 18, respectively,"and are adapted to embrace and be driventightly on to the flanges of the supporting beam or joist 10 so as to be securely held thereby. The hook-shaped feet 19 and 20 are preferablyso constructed and arranged as to permit of their free ends being readily inserted between the edges of or through openings which may be cut in the metal lath 11 to receive them, and also to permit of their being readily slipped over the flange of the beam or joist. tering or reinforcement for the floor slab, may be clamped between the feet 19, 20, and the top of the beam, if so desired.

The bights 21 between the sides of the U-shaped seat 16 and the supporting legs .17 and 18 are adapted to receive suitable driven The metallic lathing or other cen- 9 fastenings 22, as for instance nails, to hold the screed or nailing strip 12 securely in the seat against anything tending to displace it lengthwise or lift ittherefrom.

In the form of invention illustrated in Figs. 3 and .4, the support 23 has a seat 24 disposed crosswise of the beam flange for the nailing strip or screed 12, and the hook shaped feet 25 face in opposite directions, and i beam or joist; its small size permitting its use between the edges of or through openings in the lath or centering and forpositioning or securing the latter in place during construction of the fioorpanel; and the rigid ity with which it supports the screed or nailing strip at the proper distance from the lathor centering.

My invention is not'restricted to the shape or construction shown and described, nor is it restricted to use with a floor otthe type disclosed, but is susceptible of various changes in construction, shape, and uses.

What I claim is: j r

1. A support for screeds or nailing strips, for use in connection with flanged beams or joists, comprising a chair-like device formed of a single piece of wire having a U-shaped portion for receiving the screed or nailing V strip, the upwardly extending extremities of the U-shaped portion being reversely bent and extending downwardly below the U- shaped ortion thereby to constitute supporting eg portions, and angularly extending hook-shaped feet connected to said leg. portions, said hook-shaped feet being adapt ed to engage over and be supported by a flange of the beam or joist to position said U-shaped portion above the beam flange.

2. A support forscreeds or nailing strips, i for use inconnection with flanged beams or joists, comprising a chair-like device formed of a single piece of Wire having a U-shaped portion-tor receiving the screed or nailing strip, the upwardly extending extremities of the U-shaped portion being reversely bent and extending downwardly thereby to const-itute supporting leg portions, and angularly' extending hook-shaped feet connected to said leg portions, said hook-shaped feet being adapted to en age over and be supported by a flange oi the beam or joist, the bight between the legs of the U-shaped portion and the supporting legs constituting a seat for receiving suitable driven fastenings for locking the screed or nailing strip to said support. i

' 3. A centering clip and screed support for flanged metal beam concrete slab floors having centering arranged over-the beams upon which the slab rests, said clip-support having "a U-shape body constituting a chair for the screed and having its sides rebent to constitute legs, the ends of the leg portions being provided with laterally ex tending feet with their-ends bent under to formhookstor embracin the edge of a beam flange, said feet and hoo s being adapted to penetrate the centering and engage a'fiang e of a supporting beam to secure the centering and space the screed above the centering;

In testimony whereof, I have signed my name to thisspecification.
